Chemistry is an extremely significant field of study. In the pharmaceutical industry chemistry plays an important role in formulating the drug. Nowadays , when a drug is to be synthesized everyone is looking towards the simple and non-tedious chemical reaction which can be done by using less use of materials, In the past decades, the approach of making organic reactions sustainable and innovative , various new methodologies by making it solvents or catalysts-free and applying alternative energy sources such as microwaves, sonication, conventional and room temperature heating conditions, mechanochemical mixing, and high-speed ball milling are becoming popular. All are approaching towards the Green Chemistry method which provides “Green” paths for different synthetic routes using nonhazardous solvents and environmental- friendly chemicals. By application of this approach the synthesis of bromo acids has been done using the sonication process.
